Research brief: Tickling climate models reveals their bad behaviour

March 22, 2021 3:35 pm Published by Comments Off on Research brief: Tickling climate models reveals their bad behaviour

In this work CLEX researchers aim to understand a few popular ways to parameterize convection. They extracted one vertical column from five different GCMs and lightly tickled (perturbed) it and then observed the responses.

The known unknowns of climate change

Lee Constable interviews Prof Christian Jakob about what we don't know about climate change for her channel on the Cimpatico Studios platform, Climate Australia.

Research brief: tropics and SOUTHERN HEMISPHERE subtropics were drier in the mid‑Pliocene Warm Period

November 2, 2020 2:28 pm Published by Comments Off on Research brief: tropics and SOUTHERN HEMISPHERE subtropics were drier in the mid‑Pliocene Warm Period

New study shows November-to-March precipitation (when rainy season peaks over most of the Southern Hemisphere land mass) was significantly reduced both in the Southern Hemisphere tropics and subtropics due to a weakening of the subtropical convergence zones during the mid-Pliocene Warm Period.

Research brief: Tropical rainfall modelling errors decrease slowly, but storm resolving models may be the future

October 23, 2020 10:24 am Published by Comments Off on Research brief: Tropical rainfall modelling errors decrease slowly, but storm resolving models may be the future

An international team including CLEX researchers examined models used by the Intergovernmental Panel for Climate Change (IPCC) over three model phases linked to IPCC reports – CMIP3, CMIP5, and the most recent, CMIP6, to see if they improved representation of tropical rainfall.

Research brief: The Sensitivity of Atmospheric River Identification

October 20, 2020 9:43 am Published by Comments Off on Research brief: The Sensitivity of Atmospheric River Identification

CLEX researchers explore the challenges of identifying atmospheric rivers and find that detecting these events is highly variable according to resolution, and choice of the integrated water vapour transport thresholds. The uncertainties in a single detection method and data parameters may be as large as uncertainties across AR detection methodologies.

Researchers call on Australian citizen scientists to collect storm data

Australia researchers are calling on storm chasers and members of the general public fascinated by severe weather to take part in a citizen science project that will help better capture the occurrence of extreme weather events and improve our ability to forecast them.

Research brief: Where does Australia’s rain come from?

September 4, 2020 8:46 am Published by Comments Off on Research brief: Where does Australia’s rain come from?

Where does our rain come from? For a drought-prone continent like Australia, and a country with communities and industries affected by drought and flooding rains, the answer to that question is of vital importance.
